.SH "Detailed Description"
.PP 
A class which draws a coordinate grid\&. 

The \fBQwtPlotGrid\fP class can be used to draw a coordinate grid\&. A coordinate grid consists of major and minor vertical and horizontal gridlines\&. The locations of the gridlines are determined by the X and Y scale divisions which can be assigned with \fBsetXDiv()\fP and \fBsetYDiv()\fP\&. The \fBdraw()\fP member draws the grid within a bounding rectangle\&.

.SS "void QwtPlotGrid::draw (QPainter *painter, const \fBQwtScaleMap\fP &xMap, const \fBQwtScaleMap\fP &yMap, const QRect &canvasRect) const\fC [virtual]\fP"

.PP
Draw the grid\&. The grid is drawn into the bounding rectangle such that gridlines begin and end at the rectangle's borders\&. The X and Y maps are used to map the scale divisions into the drawing region screen\&.
